Wiring Requirements
To ensure intrinsic safety is maintained it is required that the installer follow these guidelines when connecting
sensors to the SignalFire node. See pictures for proper wire routing examples.
-
Strip the wires so that there is minimal exposed un-insulated wire when inserted into the screw
terminal.
-
All wiring should be neat and orderly.
Sensor Connection
Connect the Thermocouple wires to the interface board. Any error with the thermocouple or interface board
will be shown in the Status register. See table on Page 9 for details.
The polarity of the wires matters and the red wire is not necessarily positive.
Consult the manual for your specific
thermocouple for more details.
